My watch has been working virtually flawlessly ever since I got it... once, it seemed to get stuck on the blurred screen as a result of me swiping to delete a notification at exactly the same time as another one came in. Only solution was to reboot. Then today, I had a strange one, where the watch would activate, but the second I touched the screen, it would turn off. Rotate wrist, or press the digital crown would turn it back on...but again, the moment I touched the screen it would turn off....I left it for a while, charged it for a while etc...but no..the only cure was a reboot. Still..I've had it two months so it's doing better than my phone!!
